San Francisco Giants at San Diego Padres (2026-08-01). Tyler Mahle vs Walker Buehler at Petco Park.

Starters — Tyler Mahle enters with a 4.96 ERA and 1.40 WHIP over 89 innings, with 8.09 K/9, 3.54 BB/9, and 1.31 HR/9. His last three starts were encouraging: 6.0 innings with 0 earned runs on July 27, 5.0 innings with 3 earned runs on July 21, and 7.0 innings with 1 earned run on July 11. The recent form is better than the full-season line, even with the listed trend still down. Walker Buehler has a 5.13 ERA and 1.41 WHIP across 100 innings, with 8.19 K/9, 3.78 BB/9, and 1.17 HR/9. His last three starts were 5.1 innings and 2 earned runs on July 26, 5.2 innings and 2 earned runs on July 21, and 2.0 innings with 4 earned runs on July 11. His recent results also look steadier than the season numbers, though the broader trend remains down.

Teams — San Francisco has a .723 OPS, .253 batting average, and 461 runs scored. The Giants have been the stronger offensive club by OPS and average, but their pitching staff carries a 4.36 ERA and 1.35 WHIP, which can leave less margin if traffic builds on the bases. They are 5-5 over their last 10 games. San Diego has a .695 OPS, .235 batting average, and the same 461 runs scored, suggesting a less efficient offense overall but similar run production to this point. The Padres hold the better team pitching profile with a 4.13 ERA and 1.32 WHIP, and they come in on a 7-3 run over their last 10, which points to better recent team form.
